Answer: The first number that appears in both sequences is 28.

Step-by-step explanation:

Let's write down numbers from each of the sequences

Sequence 1) We need to start from 7 and multiply 4

7x4=28, 28x4=112

The sequence is 7,28,112...

Sequence 2) We need to start from 8 and add 5

5+8=13, 13+5=18, 18+5=23, 23+5=28

The sequence is 8,13,18,23,28...

They both have 28

28 is the first number that appears in both sequences.

<u>multiply by 4 starting from 7</u>

  • First sequence: 7 * <em>4</em> = <u>28</u> *<em>4</em> = 112 * <em>4</em> = 448

<u>add 5 starting from 8</u>

  • Second sequence: 8 + <em>5</em> = 13 +<em> 5</em> = 18 + <em>5</em> = 23 +<em> 5</em> = <u>28</u>

The actual length of side y is 22cm. Use the scale drawing to find the length of side x.
kozerog [31]

Given:

The actual length of side y is 22cm.

To find:

The length of side x by using the scale drawing.

Solution:

We know that the corresponding sides of original figure and scale drawing are proportional.

\dfrac{x}{1.8}=\dfrac{y}{1.4}

\dfrac{x}{1.8}=\dfrac{22}{1.4}

x=\dfrac{22}{1.4}\times 1.8

x\approx 28.286

Therefore, the length of side x is about 28.286 cm.
